How much power do you get from a steam turbine?
Depends on the turbine
How much steam is required to produce 5 MW power in steam turbine?
How much steam is required to produce 5 MW power in steam turbine?In fully condensing turbine we will need 20 TPH steam required to generate for 5MW
How much does a small steam turbine cost?
That would depend on the type and size of turbine.
How does a steam engine differ from a steam turbine?
Technically a steam turbine is a particular type of steam engine. A classic steam engine usually refers to a reciprocating steam engine, which uses a piston and crank arrangement, where pressurised steam (from the boiler) forces the piston through its stroke, producing output power. A steam turbine produces power with pressurized steam expanding to high velocity, and impinging on turbine blades which produce rotational output power. A steam turbine can be considered similar to a windmill, although steam turbines typicaly rotate much faster, and often have many stages of steam expansion within a single machine.
How much pressure behind the wheel case in steam turbine?
Do not read this answer or Weegee will get you!
How much electricity does one steam turbine make in a sec?
Steam-turbine's electric outputs range drastically. They can put out anywhere from 750 W to 1.5 GW (1,500,000,000 W).
Why used hogger and ejector in steam turbine?
A steam turbine condenser equipped with ejectors is usually fitted with two ejectors. The larger of the two is called the hogger and the smaller the huffer. Steam turbines are designed for efficiency and thus attempt to extract as much energy from the steam passing thru as is physically possible. Energy is extracted as both temperature and pressure decrease. The lower the temperature and pressure at the steam turbine's exhaust the more energy can be extracted from the steam. For this reason it is desirable for the steam turbine condenser (the exhaust) to be at the lowest temperature and pressure possible. The hogger, or hogging jet, is a large steam powered ejector that causes the steam condenser to operate under a near perfect vacuum whilst the steam turbine is in the start-up phase. In steady state operation the cooling effect of the condenser cooling water of the steam causes the condenser to operate under a nearly self sustained vacuum. The hogger is necessary in the start-up phase to prevent steam from condensing to water in the final stages of the turbine before the steam flow and cooling effect of the condenser can establish vacuum. The huffer or huffing jet runs continuously whilst the turbine is operating to remove any non-condensable gasses (i.e. air) that might leak into the condenser. It is nearly impossible to perfectly seal a condenser and turbine from air-in leakage. It should be noted that modern, large steam turbines do not employ steam ejectors to establish and maintain condenser vacuum. Modern designs utilize motor driven mechanical vacuum pumps.
How do you calculate only turbine efficiency not turbine cycle efficiency?
by calculating the inlet steam enthalpy-outlet steam enthalpy we will know the total kcal consumed for output mw required kcal for 1 kwh=860 now campare this with your turbine kcal for 1kwh now you came to know how much is your turbine efficiency................................................................................
A steam turbine has an efficiency of 40 percent A steam engine has an efficiency of 25.0 percent Suppose both devices are provided with 1000J of thermal energy How much more useful work will the ste?
The steam turbine will produce 400 J of output, and the steam engine 250 J. That's what the efficiency figure means.
What is the difference between steam turbine and water turbine?
The difference is that geysers are way much hotter than the steam from hot springs. The geysers can give you 3rd degree burns. But so can the steam from hot springs if you're in there to long.
How much did Titanic propller?
Titanic had three propellers. In the absence of solid proof, historians like Mark Chirnside feel that all three propellers had three blades. Steam engines drove her wing propellers and a steam turbine drove her central propeller. The turbine engine was not reversible although the steam engines were.
What is purpose of using Intermediate and Low pressure turbines in a thermal power station?
To obtain as much mechanical energy from the steam produced in the plant's steam raising units as possible, it is expanded through increasing sized turbine wheels, eventually expanding into a vacuum in the turbine condenser before condensing and returning to the steam cycle.
